Potassium Azeloyl Diglycinate description

Potassium azeloyl diglycinate offers many of the same benefits as pure azelaic acid (including the ability to improve uneven tone), with the advantage that is easier to incorporate into various types of cosmetic formulas due to its increased stability and compatibility. Of significance, potassium azeloyl diglycinate plays a role in reducing the appearance of redness and discomfort associated with sensitive skin. Potassium azeloyl diglycinate is a water-soluble ingredient obtained from the condensation of azelaic acid mixed with glycine. The glycine gives it a hydrating/moisturising effect that helps improve conditions for compromised skin. Simultaneously, potassium azeloyl diglycinate has the ability to normalize and in turn help minimise excess oil in skin. This can help with skin issues associated the overproduction of sebum (think clogged pores, breakouts, etc.). More research is necessary to determine the concentration range needed to produce optimal results, but from the studies currently available as well as information from ingredient suppliers, we can conclude that a 0.5% concentration is beneficial for soothing skin, while amounts between 2-3% can help fade skin discolourations and influence sebum.
